team-attention Sindoh D451 Printer Setup
Install the Sindoh D451 (CM3035) multifunction printer on macOS. Follow these steps in order.
Configuration
- Default Printer IP: 10.90.36.100 (D2SF 사무실 기본값)
- If the default IP does not respond to ping, ask the user: "프린터 IP 주소를 알고 계신가요? 기본값은 10.90.36.100입니다."
Step 1: Check Current State
Run these diagnostic commands to understand the current environment:
# macOS 버전 확인
sw_vers
# 기존 설치된 프린터 확인
lpstat -a 2>/dev/null || echo "프린터 없음"
# 신도리코 드라이버 설치 여부 확인
lpinfo -m 2>/dev/null | grep -i 'sindoh.*451\|sindoh.*CM3035'
# 프린터 네트워크 연결 확인 (IP는 Configuration 참고)
ping -c 2 -W 2 10.90.36.100 2>/dev/null
If ping fails, check if the user is on the correct network (office Wi-Fi/LAN). Ask: "사무실 네트워크(Wi-Fi 또는 유선)에 연결되어 있으신가요?"
Step 2: Driver Installation
Check if the D451 PPD is already available:
lpinfo -m 2>/dev/null | grep -i 'sindoh.*451\|sindoh.*CM3035'
If D451 PPD is found, skip to Step 3.
If D451 PPD is NOT found, guide the user to download the driver:
- Open the download page automatically:
open "https://www.sindoh.com/support/download/d451" - Based on
sw_versoutput, tell the user which OS to select:- macOS 15.x → "Mac OS 15.X"
- macOS 14.x → "Mac OS 14.X"
- macOS 13.x → "Mac OS 13.X"
- If version is not listed, advise: "해당 macOS 버전의 드라이버가 없습니다. IT 담당자에게 문의해주세요."
- Download and install the SINDOH_D450_CM.PKG file (D451과 D450은 같은 드라이버를 사용합니다)
IMPORTANT: The download page loads dynamically via JavaScript. Direct API access is blocked by Cloudflare. The user MUST use a browser to download.
STOP and WAIT here. Ask the user: "드라이버 설치가 완료되면 '설치 완료'라고 말씀해주세요."
After the user confirms, verify the PPD is available:
lpinfo -m 2>/dev/null | grep -i 'sindoh.*451\|sindoh.*CM3035'
Expected output: Library/Printers/PPDs/Contents/Resources/SINDOH_D451_CM3035.gz SINDOH D451/CM3035 PS
If PPD is still not found, the installation may have failed. Ask the user to try again.
Step 3: Add Printer
Add the printer using lpadmin. If the command fails with a permission error, retry with sudo and tell the user they may need to enter their Mac login password.
lpadmin -p "SINDOH_D451" \
-E \
-v "lpd://10.90.36.100" \
-m "Library/Printers/PPDs/Contents/Resources/SINDOH_D451_CM3035.gz" \
-D "신도리코 D451" \
-L "사무실"
Verify the printer was added:
lpstat -p SINDOH_D451 -l
Step 4: Set as Default Printer
Before changing the default printer, check the current setting and ask:
lpstat -d
Ask the user: "현재 기본 프린터가 [현재값]으로 설정되어 있습니다. 신도리코 D451을 기본 프린터로 변경하시겠습니까?"
If the user agrees:
lpoptions -d SINDOH_D451
Step 5: Test Print
Print a test page to verify the setup:
echo "Sindoh D451 Test Print - $(date)" | lp -d SINDOH_D451
Or if the user has a specific file to print:
lp -d SINDOH_D451 /path/to/user-file.pdf
Check print job status:
lpstat -W all | grep SINDOH_D451
After test print, tell the user: "테스트 인쇄가 전송되었습니다. 복합기에서 출력물이 나오는지 확인해주세요."
Troubleshooting
If the printer doesn't respond:
# 네트워크 연결 확인
ping -c 3 10.90.36.100
# 인쇄 대기열 확인
lpstat -W all
Explain results to the user in plain Korean.
To delete and reinstall the printer, MUST ask user confirmation first: "프린터 설정을 삭제하고 다시 설치하시겠습니까?"
If confirmed:
lpadmin -x SINDOH_D451
Then restart from Step 3.
